This stud serves well for the size of most double sided PCB Board prototype. Isolate your electronics!
I recommend using the 2.2 mm stud for firmness just beware that it'll be dificult to remove. The 2.0 one is less firm but easier to remove.
Print at .2mm at almost 100 percent, this little guy might experience some forme when pushing it in.
If the Stud is not holding very well, print the one with tapper and force it down a little bit to make it get stuck.
